BACKGROUND OF THE INVENTION Field of the Invention

The present invention is directed generally to an eyewear platform, and more particularly, to the design of a releasably attachable augmented reality (AR) system that meets the demands of consumers and enterprise, while providing features including, but not limited to, augmented reality or mixed reality. Additionally, certain aspects of the invention disclosed herein can be applied to augmented reality or mixed reality eyewear in general.

It is an adage in the optical industry that fashion trumps function. Even if a type of eyewear is highly functional, if it is not fashionable, the eyewear will not be purchased in quantity by consumers. There are literally hundreds, if not thousands, of eyewear frame styles. (See, e.g., FIGS. 5, 6.) Consumers like and demand selection when picking out new eyewear. Electronic eyeglasses of all types have suffered from this consumer hurdle. Building electronics into the eyeglass frame increases the cost of goods, cost to the consumer, and thickness and weight, and reduces the fashion selection of eyewear available for consumers to choose from. By way of example only, Augmented Reality (AR) eyewear (mainly in the form factor of a headset or goggles) today can weigh up to 500 grams, compared to customary eyeglasses which weigh 20 grams to 40 grams. Such AR headsets or goggles retail for up to $3,000 or more. They are bulky, heavy, not fashionable looking, and expensive. Smart eyeglasses with a heads-up display are available in a very limited number of styles and colors. What is needed is a new platform for providing AR and or Mixed Reality (MR) for consumers and enterprise to use, while maintaining an acceptable fashion, look, weight, selection of eyewear, and cost.

Description of Related Art

As computer systems have been miniaturized and have higher performance and display apparatuses and image communication technologies have advanced, wearable devices that can be worn by a user have been developed. For example, smartwatches wearable on the wrist, smart bands wearable on the head, arm, or foot, smart eyewear worn on the head, etc. have been developed.

The trend toward miniaturization of computing hardware, peripherals, as well as of sensors, detectors, wireless communication and image and audio processors, among other technologies, has helped open up a field sometimes referred to as “wearable computing.” In the area of image and visual processing and production, in particular, it has become possible to consider wearable displays that place a very small image display element close enough to a wearer's eye such that the displayed image fills or nearly fills the field of view, and appears as a normal sized image, such as might be displayed on a traditional image display device. The relevant technology may be referred to as “near-eye displays.”

Near-eye displays are fundamental components of wearable displays, also sometimes called a head-mountable device or a “head-mounted display.” A head-mountable device places a graphic display or displays close to one or both eyes of a wearer. To generate the images on a display, a computer processing system may be used. Such displays may occupy a wearer's entire field of view, or only occupy part of wearer's field of view. Further, head-mountable devices may be as small as an electronic contact lens, a pair of smart eyeglass lenses, or as large as a helmet.

A head-mountable device may provide a graphic display and may be directed to transition from one state to another, such as to transition from and “on” state to an “off” state.

Such displays may be used for Augmented Reality and/or Mixed Reality as explained herein. They are also used for Extended Reality, referred to as XR. XR is the overarching category of one or more of a smartphone, mobile Virtual Reality headset, and/or Augmented Reality unit, such as the embodiment(s) described in the current application. Accordingly, the various embodiments disclosed herein can be used for certain forms of XR.

SUMMARY OF THE INVENTION

An AR Unit is provided, whereby the AR Unit utilizes existing eyewear as an attachment platform, and whereby the AR Unit is attachable to and detachable from a plurality of different eyewear having different shapes and sizes, whereby a portion of the AR Unit rests on the top of the eyewear, and whereby the AR Unit can provide unobstructed vision when the wearer is looking straight ahead. In certain embodiments, an optical combiner of the AR Unit is located at or above the upper edge of the pupil of the wearer. Said another way, in certain embodiments the optical combiner of the AR Unit is located above, immediately above, or higher above the line of sight of the wearer. (See, e.g., FIGS. 28-30) In other embodiments, the optical combiner is located within the line of sight of the pupil 2910. (See, e.g., FIG. 29.)

The AR Unit can be comprised of the following major parts: 1) AR main unit, 2) AR unit housing, 3) AR unit housing covering, 4) AR unit electrical conductive tether and electronic module that can, by way of example only, reside behind the wearer's head or neck, 5) Optical Engine(s), 6) Light Engine(s), 7) Vision System, 8) associated electronics, 9) camera(s) or image capture device(s), and 10) auditory system.

Utilizing the invention, a limited number of AR Unit shapes can fit most eyewear frame styles and sizes. In fact, five or fewer AR Units can fit most eyewear frame styles. This can be accomplished, by way of example only, by one of: the provider of the AR unit at the point of sale or the purchaser of the AR Unit for his or her eyewear, whether the eyewear be new eyewear or existing eyewear. The AR Unit's main body can fit on the top of an eyewear frame and can be adjusted or conformed to the top contour or shape of the eyeglass frame front's top. In certain embodiments, compressible material can be positioned between the top of the eyewear frame and the bottom of the AR Unit, or in a recess in the bottom of the AR Unit to wholly or partly fill in any open space that may exist or help achieve acceptable fit. In other embodiments, a façade can be placed beneath the AR Unit and above the top of the eyewear frame bridge to fill in any open space that may exist.

The AR Unit can provide monocular or binocular augmented reality. In certain embodiments, the horizontal length of the AR Unit (main body) is the same as or is shorter in length dimension than the horizontal length dimension of the eyewear frame front that is supporting it, and the middle of the horizontal AR Unit (main body) dimension is of a greater vertical height dimension than either end of the horizontal dimension length of the AR Unit (main body). (See, e.g., FIG. 8.) The front of the AR Unit main body can extend forward in front of and above the eyewear frame front to which it is attached. The rear of the AR Unit main body can extend slightly rear of and above the frame of the frame front to which it is attached. In most embodiments, but not all, the front of the AR Unit's main body extends forward from the AR Unit's main body more than that of the back of the AR Unit's main body relative to the eyewear frame front to which it is resting.

In certain embodiments, five or fewer AR Unit main body designs having one or more flex joints or made of a flexible or shapeable material can fit upwards of between 66.67+% and 80%, for example, of all eyewear styles and sizes. (See, e.g., FIG. 7.) In certain embodiments, the AR Unit main body is made of a flexible material that houses one or more rigid electronic and/or optical module(s). In certain embodiments, the AR Unit main body has a recess in the bottom side of the AR Unit. The AR Unit main body can have a recess that is of a length that accepts a portion of a top of an eyeglass frame. The AR Unit main body can have a recess that is of a length that accepts the top of an eyeglass frame. In certain embodiments, the bottom of the AR Unit can accept a pin from a conformable or compressible material. (See, e.g., FIGS. 9, 10.) The recess can accept a male ridge located on the top surface of a conformable or compressible material. (See, e.g., FIG. 9.) In certain embodiments, the AR Unit includes a permanent, integral, or removable conformable or compressible material. (See, e.g., FIG. 13.) In certain embodiments, the conformable or compressible material has a male ridge on its superior top surface that fits within a female recess of the bottom of the main AR Unit portion (see, e.g., FIG. 13), or the conformable or compressible material has a female recess that is on the lower bottom surface of the compressible material that fits over a portion of the top edge of the eyewear. The AR Unit main body may comprise a conformable or compressible material that extends across the majority of the AR Unit main body (see, e.g., FIG. 13), or that is located above the bridge of the eyewear (see, e.g., FIG. 14). The compressible material can be in one or more pieces.

In other embodiments, a bendable member is housed within or attached to a flexible portion of the AR Unit. The flexible portion of the AR Unit rests on top of an eyewear frame front. The bendable member can have little to no material memory, meaning that once it is bent it does not return to its original shape. The bendable member can be reshaped so to reshape the flexible portion of the augmented reality device. In aspects, the AR Unit main body is constructed of materials that permit being reshaped by a third party or the wearer to fit his or her eyewear frame and/or to allow for a customized look preferred by the wearer or third party when attached to his or her eyewear. It should be pointed out, that this patent disclosure anticipates that the seller of the AR Unit and/or an optical technician can also fit or shape the AR Unit for the eyewear of the wearer to the satisfaction of the wearer. Also, this patent disclosure anticipates that the purchaser can also fit or shape the AR Unit for his or her eyewear to their satisfaction.

In still other embodiments, the covering of the AR Unit is bendable or shapeable, while the internal electronic module and/or electronics are left largely unaltered. This permits the AR Unit's bottom to be reshaped without affecting other parts of the AR Unit. In other embodiments, the electronics within the AR Unit are housed within mostly rigid structures. These structures are divided into separate structural compartments permitting the AR Unit to be reshaped while leaving the electronics largely intact.

The AR Unit main body houses one or more electronic module(s) and thereby fully or partly covers and/or houses the electronic module(s). The AR Unit main body can house one or more of: conformable, bendable, formable, and/or malleable members. In aspects, when a single conformable member is utilized, the electronic module or modules are separate from the single conformable member. (See, e.g., FIGS. 44, 51-52.) The AR Unit Body may house an electronic module(s) having one or more of: conformable portions, malleable portions, and/or bendable portions. The one or more of: conformable, malleable, bendable, and/or formable member(s) or portion(s), can be adjusted to shape the AR Unit main body or portions of the body so that it is complementary to the eyewear frame front, on top of which the AR main body or AR Unit rests. The bendable materials can be made of any material that can be bent to a shape while retaining the shape to which it is bent; by way of example only, a thin metal. Such bendable materials having little to no memory, by way of example only, can include: tin, aluminum, polycarbonate, PMMA, or polystyrene. The following are, by way of example only, flexible materials that the AR Unit main body or its outer covering can be made of by way of example only: polyterephthlate, urethane, polybutadiene, polyisoprene, cross linked hydrogel, and/or rubber. The following are, by way of example only, malleable materials that may be used to shape the AR Unit main body. The malleable materials that have re-formable memory, by way of example only include: malleable thermosets based on polyimine networks, cross-linked polycaprolactone, or polyurethanes.

In certain embodiments, the AR Unit main body comprises an arm or arms. Each arm secures the unit to one of the two eyewear temples. Each arm can be attached to an eyewear temple by way of any mechanical attachment means, by way of example only, strap, hook, snap, magnet, male/female interface, and/or Velcro. In one embodiment, by example only, an arm can have a series of apertures which permit the arms to be adjusted. (See, e.g., FIGS. 16-17.) An arm can have two or more apertures. The apertures can be circular, elongated or of any shape. A male member that is connected to the eyewear temple permits engaging with an aperture of the arm. By choosing different apertures, the arms can be adjusted in length. In other embodiments, the arms can comprise a small magnet which then engages with a track comprising a ferromagnetic material or another magnet located on or about the temple. In a preferred embodiment, the arm attaches directly or indirectly to the inside side of the eyewear temple. The track can be attached to the eyewear temple or incorporated within the side of the eyewear temple. In other embodiments, the arms can comprise a ferromagnet material which then engages with a magnet located on or about the temple. In a preferred embodiment, the arm attaches directly or indirectly to the inside side of the eyewear temple. The track can be attached to the eyewear temple or incorporated within the side of the eyewear temple. In still another embodiment, two magnets can be used; one on the arm, and one that is embedded in or attached to the eyewear temple. In certain embodiments, the arm(s) are attached directly to the hinge which attaches a temple to the eyewear frame front.

In certain embodiments, the arm(s) can be attached to the AR Unit main body by, for example, a hinge or swivel joint. (See, e.g., FIG. 16.) This allows an arm to be rotated up or down depending upon the manner to which it attaches to the eyewear temple. For clarity, the arms of the AR Unit can be adjustable in length and/or also in positioning. This permits for attaching the AR Unit main body to a wide variety of different styles, sizes, and shapes of eyewear.

The AR Unit main body can be expanded or shortened horizontally to fit a larger or smaller frame front, respectively. The manner which the AR Unit's horizontal length can be expanded or shortened is, by way of example only, a pin or pins that pull in or out of each of the horizontal ends of the AR Unit's main body. In other embodiments, the horizontal length of the AR Unit's main body can be expanded or shortened by way of the covering of the AR Unit's main body being separated into two or more sections in a manner which it can be pulled apart or pushed together. In preferred embodiments, the AR Unit main body supports one or more optical windows, including two optical windows. When two optical windows are utilized, in aspects, one optical window can be up to 60 mm wide (horizontally) and up to 50 mm tall (vertically). In certain embodiments, one optical window can be used. In other embodiments, each optical window can be 20 mm or less wide (horizontally) and 20 mm or less tall (vertically). When one optical window is utilized for both eyes, the one optical window can be up to 150 mm horizontally and up to 50 mm tall (vertically). An optical window or a portion of the optical window(s) can be, support, comprise, include, or act as a partial reflector or a beamsplitter. For purposes of clarity, a partial reflector as used herein is meant to facilitate the same function; namely, to allow the transmission of a certain amount of light while reflecting a certain amount of light (see, e.g., FIG. 56A). An optical window or a portion of the optical window(s) can be, support, comprise, include, or act as an optical combiner or combiner. For purposes of clarity, an optical combiner and combiner as used herein are meant to facilitate the same function; namely, to cause two or more images to be superimposed on one another or within the same view, such as when a virtual image is combined with a real image as perceived by a wearer of a system. In certain embodiments, an optical window can have a width on one end of 3 mm to 7 mm for a certain distance and then enlarge to that of a 7 mm to 15 mm square, round, circle, oval, or some other shaped zone to which the pupil of the wearer's eye will look through. In certain embodiments, an optical window can be 10 mm-60 mm wide. In certain embodiments, an optical window can be 10 mm-50 mm high (vertically). An optical window can be taller vertically than it is wide horizontally. (See other possible dimensions, shapes, and sizes in, e.g., FIGS. 18-21.) The thickness of the optical window can be 0.25 microns to 3.0 mm thick. The materials can be made of, by way of example only, transparent soft, semi-rigid, and/or rigid materials. An optical window can be shorter vertically that it is wide horizontally (see, e.g., FIG. 31). In certain embodiments, one long horizontal optical window can be used that wholly or partly covers both eyes and is continuous over the nose of the wearer (see, e.g., FIGS. 32-33). When one optical window is utilized, a notched area is provided in the bottom edge of the optical window for clearing an area around the nose of the wearer (see, e.g., FIGS. 32-33). In this case, the long continuous optical window can be over 100 mm in the horizontal dimension. When the optical window is one long continuous unit, certain portions of the optical window can comprise, support, include, or have embedded a combiner(s), beamsplitter(s), or partial reflector(s). In certain embodiments, the previously disclosed one long continuous optical window can be split over the bridge of the nose to break the window into two windows so that each can be adjusted independently of one another (see, e.g., FIGS. 31, 50).

In certain embodiments, an optical window and/or optical combiner can be that of a top down optical window or optical combiner. The optical window and/or optical combiner can be attached to the AR Unit main body and extend down and in front of a lens housed by the eyewear frame to which it is attached or is resting thereupon. In certain other embodiments, the optical window and/or optical combiner can be attached to the AR Unit main body and extend down and behind a lens housed by the eyewear frame to which it is attached or is resting thereupon. In certain other embodiments, the optical window and/or optical combiner can be incorporated within the lens housed by the eyewear.

In certain embodiments, the bottom edge of the optical window is located at or above the top edge of the pupil of the eye(s) of the wearer. In other embodiments, the bottom edge of the optical window is located such to cover the bottom edge of the pupil. When the bottom edge of the optical window is located at or above the top edge of the pupil of the eye of the wearer, the wearer can experience unencumbered vision with normal gaze when looking straight ahead. When the bottom edge of the optical window is located at or above the top edge of the pupil of the eye of the wearer, the line of sight of the wearer is unencumbered by the optical combiner. In such an embodiment, when the wearer desires to see an augmented or mixed reality image, the wearer tilts his or her chin down between 5 and 45 degrees while keeping his or her eyes looking straight ahead in a horizontal manner relative to the ground on which they are standing (see, e.g., FIG. 57).

An optical window, or portions thereof, can made of a transparent, mostly transparent, translucent, mostly translucent, semi-transparent, transmissive, and/or partially transmissive material. All or a portion of the optical window can be made of a light transmission changing material such as, by way of example only, photochromic material, electrochromic material, and/or thermochromic material.

In certain embodiments, an electrical conductive tether and electronic module is part of or connected to the AR Unit. These can, by way of example only, reside behind the wearer's head or neck. In aspects, the electrical conductive tether connects certain electronics not housed in the AR Unit main body with those housed in the AR Unit main body. This allows for electronic components to be offloaded or located separately from the AR Unit main body and housed on or within the electrical conductive tether and electronic module. By way of example only, one or more of the following can be electrically connected to the electrical conductive tether or electronic module: power source, main power source, rechargeable battery, battery, coil, source of wireless communication, controller, transceiver, transmitter, receiver, GPS, CPU, memory storage, flash memory, random access memory, EEPROMs, earbud, hearing aid, assisted hearing device, wifi chip, Bluetooth chip, vibrator, communication system, antenna, audio system, radio, sensor, ASIC, switch, auditory system, sensor(s) and/or image processor. This reduces the size and weight of the AR Unit main body. This reduced size helps with making the AR Unit more fashionably acceptable and/or comfortable to the wearer when attached to the eyewear worn by the wearer. Also, the reduced weight helps with comfort of wearing the AR Unit when attached to the eyewear worn by the wearer.

The AR Unit can comprise an auditory system. The auditory system can utilize ear buds. The ear buds can be connected by a wired connection to the AR Unit. When wired to the AR Unit, the ear buds connect in most but not all cases to the electronic tether. The ear buds can be wirelessly connected to the AR Unit. The auditory system can utilize bone conduction for audio transmission. A personal assistant can be part of the auditory system.

A fourth embodiment disclosed herein is that of a wearable apparatus capable of providing a virtual image, wherein the apparatus is an AR Unit, wherein the AR Unit's main body supports one or more light engine(s) for lighting an image perceived by the wearer, wherein the lighted image is perceived to be a virtual image, wherein one or more optical engine(s) causes the wearer of the apparatus to perceive a virtual image mixed with a real image, wherein the apparatus comprises an outer covering, wherein the AR Unit main body can be adjusted to fit a plurality of different eyewear frames, wherein the apparatus is releasably attachable to the plurality of different eyewear frames and wherein a façade is located beneath the bottom of the AR Unit's main body and the top of the eyewear frame front superior to the bridge of the eyewear.

The invention can be thought of in terms of several parts; for example only, the AR Unit can be comprised of three or more of the following major parts: 1) AR main unit, 2) AR unit housing, 3) AR unit housing covering, 4) AR unit electrical conductive tether and electronic module that can, by way of example only, reside behind the wearer's head or neck, 5) Optical Engine(s), 6) Light Engine(s), 7) Vision System, 8) associated electronics, 9) camera(s) or image capture device(s), and/or 10) auditory system.

In aspects, a Light Engine can comprise one or more of the following: electronic displays, such as LCD, micro OLED or micro LED (μLEDs), LED display, OLED display, OLED see-through display, DLPs, LCOS, as well as scanning display types such as a vibrating fiber, laser scanning display, laser-based projector, a lenticular (based on micro-lens arrays), focusing lens, spatial modulator, collimator, optical coupler, projector, and/or direct laser scanning into or onto the retina.

In aspects, a Vision System comprises one or more of the following: spectacle lens(es) which can be that of prescription or non-prescription, optic(s), optical combiner(s) which can have optical power or no optical power. The optical combiner is a component of the optical engine but may be considered to be part of the vision system. The optical combiner can be located behind the spectacle lens closest to the eye, embedded within the spectacle lens, on a surface of the spectacle lens, or in front of the lens away from the eye. The vision system can be monocular or binocular. The AR unit can provide a monocular augmented reality image or a binocular augmented reality image. The AR unit can provide a monocular virtual image or a binocular virtual image. The AR unit can provide a monocular mixed reality image or a binocular mixed reality image. When the AR unit provides a binocular virtual image then the number of components that create and communicate the virtual image to the wearer may comprise more than that of an AR Unit providing a monocular virtual image. By way of example only, when a monocular virtual image is communicated to the wearer, only one optical combiner is required. When a binocular virtual image is communicated to the wearer, two optical combiners are required. Said another way, a monocular AR unit requires one optical engine and one light engine, whereas a binocular AR Unit requires two optical engines and two light engines.

An optical window can be a transparent or mostly transparent substrate. An optical window can be made of, by way of example only, plastic or glass. An optical window can be made of, by way of example only, a rigid, semi rigid, soft, and/or flexible material. An optical window can be planar or curved. In certain embodiments, the optical window is flat. In other embodiments the optical window is curved. The curve can be similar to an eyeglass lens front surface. In still other embodiments the optical window is curved to match the front convex surface of the spectacle lens to which it sits in front of. When used as a substrate, the optical window can have the same refractive index or within the range of 0.01-0.05 refractive index units and more preferably within the range of 0.01-0.03 refractive index units of the material as the member that is attached. An optical window can transmit an image from a projector or a display, such as the embodiment shown in FIG. 56A or 56B, or an optical window can transmit an image internally through the material the optical window is made of, such as the embodiment shown in FIG. 56C (e.g., a transparent OLED display or an image created by an external display and transmitted to the optical window using an image-preserving waveguide array). An optical window can support the transmission of an image from a projector or a display, such as if it includes a partial reflector, or an optical window can support the transmission of an image, such as if it includes a see-through OLED display or an image created by an external display and transmitted to the optical window using an image-preserving waveguide array. An optical window can itself also reflect an image from a projector or display. An optical window, or portion(s) thereof, can be that of an optical combiner or combiner. An optical window, or portion(s) thereof, can support an optical combiner or combiner. An optical window can be antireflective coated on one or both surfaces. An optical window can be removably attachable to the AR Unit, such as magnetically to the AR Unit (see, e.g., FIGS. 50-52 at 5030, 5130, and 5230). An optical window can be removably attached mechanically or permanently attached to the AR Unit. An optical window can be one continuous optical window for both eyes (see, e.g., FIGS. 32-33). An optical window can be a monocular optical window for one eye. An optical combiner 3310 can take up a portion of the optical window. An optical combiner can comprise all of the optical window. One continuous optical window can be notched to fit around the nose of the wearer. One continuous optical window can have one optical combiner for one eye (monocular) or two optical combiners for two eyes (binocular). (See, e.g., FIG. 33.) When removably attached to the AR Unit, a magnetic attachment or mechanical attachment can properly align the optical communication from the light engine to the optical window. In certain embodiments, an optical window can be located in front of the eyeglass lens, furthest away from the eye of the wearer. In certain other embodiments, an optical window is located behind the eyeglass lens closest to the eye of the wearer. In still other embodiments the optical window can be embedded within the eyeglass lens housed by the eyewear.

In certain embodiments, the bottom edge of the optical window is located at or above the top edge of the pupil of the eye of the wearer. In other embodiments, the bottom edge of the optical window is located to cover the bottom edge of the pupil. When the bottom edge of the optical window is located at or above the top edge of the pupil of the eye of the wearer, the wearer can experience unencumbered vision with normal gaze when looking straight ahead. When the bottom edge of the optical window is located at or above the top edge of the pupil of the eye of the wearer, the line of sight of the wearer is unencumbered by the optical combiner. In such an embodiment, when the wearer desires to see an augmented or mixed reality image, the wearer tilts his or her chin down between 5 and 45 degrees while keeping his or her eyes looking straight ahead in a horizontal manner relative to the ground on which they are standing. (See, e.g., FIG. 57.) In FIG. 57, the wearer's line of sight 5710 is shown by the dotted line and the optical combiner is shown by 5720. As shown in the figure, when the wearer is looking straight ahead, the optical combiner 5720 is above his pupil(s) and out of the line of sight 5710. When he tilts his chin down and looks ahead, his line of sight passes through the optical combiner 5720.

In still other embodiments the optical window can cover the pupil of the wearer when the wearer is looking straight ahead. In these embodiments the optical window is larger than in the embodiments where the wearer must tilt his or her chin down to see through the optical combiner. When the optical window covers the pupil of the wearer when the wearer is looking straight ahead, the optical window can be one of: the same size as that of the eyewear frame lens outer dimensions, smaller than the eyewear frame lens outer dimensions, or larger than the eyewear frame lens outer dimensions.

Both the optical window(s) and the eyeglass lens(s) may be coated with an antireflection coating. In certain embodiments an index matching or index averaging oil can be applied between the front of the eyeglass lens and the back of the optical window to enhance light transmission between the eyeglass lens and the optical window.

An optical window can support a reflector or partial reflector. The reflector may provide optical power. A reflector having optical power can alter the focal length of the image, correct an optical aberration, magnify an image, minify an image, alter the focus of an image. The reflector can be free of optical power. An optical window can have a reflector embedded within the optical window. An optical window can have a reflector attached to its surface. The reflector can be sized to be only a portion of the optical window. The reflector can be the full size of the optical window. The reflector can be a partially transmissive mirror. A reflector can be a mirror. A reflector can be a mirror with aspheric power. A reflector can be a spherical powered mirror. The reflector can be a pin mirror. An optical window can comprise a fiber optic light bundle on the side closest to the eye. Alternatively, an optical window can comprise a fiber optic light bundle on the side away from the eye. An optical window can support a fiber optic light bundle and/or a waveguide array. An optical window can support, include, and/or comprise a waveguide array. An optical window can support, include, and/or comprise a lightguide. An optical window may be a waveguide array. An optical window may be a lightguide. An optical window can support, include, be, and/or act as a display. The display can be, by way of example only, a see-through OLED display. An optical window can support, include, be, incorporate, and/or act as a lightpipe 1910, 2110, as well as an image expander, diffractive optic(s), and/or mirror(s) 1920, 2120. (See, e.g., FIGS. 19, 21.)

An optical window can support and/or include that of a partially transparent or see-through OLED. An optical window can be, support, and/or include that of a display; the display can be, by way of example only, one of: a LCD, micro OLED or micro LED (μLEDs), LED display, OLED display, OLED see-through display, DLPs, LCOS or back lit display. An optical window can comprise an optical combiner which creates an eye box 1930, 2130. An optical window can be, support, and/or include one or more of waveguide(s), waveguide array, lightguide(s), mirror(s), lens(es), optic(s), grating(s), optical fiber(s), lightpipe(s), reflective element(s), beam splitter(s), Pupil Relay(s), segmented reflector(s), Fresnel or diffractive facet(s), microlens array, optical combiner(s), combiner(s), coating(s), and/or diffractive element(s)

An optical window can have steps on its surface. These steps can be in the upper 50% of the height of the optical window for accepting a rotating mechanical member providing upward and downward movement of the optical window. An optical window can be adjustable from one position to another, by way of example only, an optical window can be moved in one or more of the following directions: horizontally, vertically, clockwise, counter clockwise, rotated such that its bottom edge is moved further away from the front surface of an eyeglass lens or moved closer to the front surface of an eyeglass lens.

A portion of the upper 50% of the vertical height of the optical window can be opaque with the remaining up to 50% being transparent. The optical window can darken when in sunlight. An optical window can be darkened and/or lightened in light transmission. Such techniques for darkening and lighting the optical window are well known in the art. By way of example only, an optical window can be photochromatic, thermochromic, electrochromic, mirror coated, clear, darkened by dichroic liquid crystal, and/or tinted.

In certain embodiments, the AR Unit can have two optical windows and each optical window can be, include, and/or support an optical combiner. Each optical window can support one fiber optic bundle. Each optical window can support a fiber optic bundle and an optical combiner. The fiber optical bundle can be superior to that of the optical combiner.

In certain embodiments, the optical window be, include, and/or support a transparent OLED. The optical combiner can be, include, and/or support a see-through OLED. A transparent OLED or TOLED can be that of a see-through OLED. In certain embodiments the optical window can be, include, and/or or support a see-through OLED comprising a microlens array. In certain embodiments the optical window can be, include, and/or support a microlens array attached to a see-through OLED. The see-through OLED and/or microlens array can be curved in a similar manner as the front surface of the eyeglass lens to which it is in front of. Such a curve can be similar to the base curve of such eyeglass lens. When the AR Unit utilizes a see-through OLED for its optical combiner, the AR Unit's main body can be reduced in size and weight. This is due to the fact that the AR Unit's light engine and the optical engine can be reduced in number of components and size. In addition, the energy use can in most cases be reduced as well. In certain embodiments, each optical window can support a waveguide and see-through OLED. In certain embodiments, each optical window can support a lightguide and see-through OLED. In certain embodiments, each optical window can support a fiber optic bundle and see-through OLED. In certain embodiments, an optical window can support a see-through OLED. In certain embodiments, the see-through OLED is an optical combiner. In certain embodiments, an OLED is a light source for the light engine. In certain embodiments, the see-through OLED is a portion of the optical engine. In certain embodiments, the see-through OLED is the optical engine. In certain embodiments, the see-through OLED is the light source for the light engine and is also a portion of the optical engine. In certain embodiments, the see-through OLED is the light source for the light engine and is also the optical engine.

The AR Unit can support two optical combiners, one for each eye. The AR Unit can support one optical combiner. The optical combiner can be lined up relative to a pupil of the wearer.

An edge of the optical combiner can be at the peripheral edge of the virtual augmented reality bubble defined by the field of view that is created by the unit's optical combiner within a real image and can be feathered (or smoothed out) by way of a refractive index gradient formed within the material of the optical combiner effectively reducing the brightness of the augmented reality bubble at its periphery. By way of example only, if the section of the optical combiner has an index of refraction of 1.8, refractive index would transition from 1.8 at the center of the optical combiner to a refractive index of 1.5 at the outer edge of the section of the optical combiner. This change in refractive index may be applied over a length of 0.5 mm to 3.0 mm, preferably 0.5 mm to 1.0 mm. A short refractive index gradient serves to reduce the intensity of the edge without affecting the brightness of the overall virtual image. Such an index gradient can be fabricated by any means known in the art for creating such an index gradient, including by way of example only, deposition of an additional layer of a second material. Such a second layer may be of thickness 5 microns to 500 microns, preferably 25 microns to 100 microns.

When the AR Unit main body is flexed or bent to conform to the top of the eyewear frame front, this may cause the optical windows and other visual, light, and optical components to rotate out of alignment with respect to the optic axis of the eye. The optical windows, for example, could become rotated and not straight up and down vertically upon conforming the AR Unit main body or outer covering to properly fit or look best upon the top of the eyewear frame front. Should this occur, in certain embodiments, either the optical window or the connection to the optical windows can be rotated in the appropriate direction to allow for the optical windows to become realigned vertically. This adjustment requires a rotatable fixture that can rotate along one axis, two axes or three axes. Also, each optical window can be adjustable by way of rotating clockwise or counter clockwise.

In certain embodiments, the vertical height of the optical combiner of the optical window can be adjustable by way of edging the waveguide optical combiner of the optical window to the desired vertical height for a given frame eye size and style relative to the wearer's pupil. In certain embodiments the vertical height of the optical combiner is manufactured to be of the appropriate height. The displayed augmented reality image can be programmed to be displayed in relation to the usable optical combiner dimensions (vertical and horizontal) that control the field of view. In preferred embodiments, the bottom edge of the optical combiner is set above the top edge of the pupil at primary gaze. The optical window or optical combiner may also be angled such that the bottom of the optical window or optical combiner can be rotated forward and then up and over, as shown at 2230 in FIG. 22. In certain embodiments, the bottom edge of the optical window or optical combiner (when fit above the top edge of the pupil of the eye of the wearer) can be rotated away from the front of the eyewear lens. By doing this, it offsets certain of the angle of the head tilt when the wearer's chin is tilted down and the eyes continue to look forward and straight ahead to experience augmented reality. By offsetting certain of the angle of the head tilt and having the bottom edge of the optical window or optical combiner rotated away from the front of the eyewear lens, the line of sight of the wearer strikes the optical combiner in a mostly perpendicular manner. (See, e.g., FIG. 55.) In certain cases, this is preferred and in other cases the bottom edge of the optical combiner is not rotated away from the eyeglass lens to which it sits in front of.

As shown in FIG. 22, optical window(s) can be rotated counterclockwise 2210 and/or clockwise 2220 while supported by the AR Unit. When one optical window is used, an optical window can rotate so that the bottom of the optical window located nearest the pupil of the eye is rotated temporally. When two optical windows are used (one in front of each eye, for example), each optical window can rotate so that the bottom of the optical window located nearest the pupil of the eye is rotated temporally. Also, when two optical windows are used (one in front of each eye, for example), each optical window can rotate so that the bottom of the optical window located nearest the pupil of the eye is rotated nasally. An optical window can be moved horizontally and/or vertically while supported by the AR Unit. The optical window can be rotated along the Z axis when not in use such that the bottom of the optical window is rotated out and up and back.

An optical window(s) can be moved nasally and/or temporally while supported by the AR Unit. When the optical window is moved horizontally, it generally is moved to align the wearer's pupillary distance. The pupillary distance is the distance between the wearer's pupils when looking at a particular distance (which is usually far, intermediate and near) measured under a standard level of illumination. An optical window can be moved vertically and/or horizontally when supported by the AR Unit. An optical window can be moved automatically or semi-automatically by the AR Unit. An optical window can be moved mechanically or manually by the wearer of the AR Unit. The optical window or optical windows can be moved out of the field of view of the wearer when the AR Unit is not being used thus allow for the wearer to have unencumbered vision when looking straight ahead or otherwise. In certain embodiments, the optical window can be magnetically detached from the AR Unit and magnetically reattached to the AR Unit such that the proper optical alignment is maintained. The mechanism for effecting the movement of the optical window may comprise using a sensor, a controller, and/or a motor. The motor can be a micro motor. The motor can be mems device. The AR Unit can support one or multiple prisms. The AR Unit can support one or multiple reflectors. The AR Unit can support one or multiple illumination sources. The AR Unit can support one or multiple optical engines. The AR Unit can support one or multiple light engines.

The AR Unit can comprise one or more of the following: waveguide(s), waveguide array(s), lightguide(s), mirror(s), lens(es), optic(s), collimator(s), microlens array(s), optical coupler(s), grating(s), optical fiber(s), lightpipe(s), reflective element(s), beam splitter(s), Pupil Relay(s), segmented reflector(s), Fresnel or diffractive facet(s), optical combiner(s), combiner(s), coating(s), diffractive element(s), optical window(s), and/or optical substrate(s).

The AR Unit can comprise one or more of the following: electronic displays, such as LCD, micro OLED or micro LED (mLEDs), LED display, OLED display, OLED see-through display, TOLED, DLPs, LCOS, as well as scanning display types such as a vibrating fiber, laser scanning display, laser-based projector, a lenticular (based on micro-lens arrays), focusing lens, spatial modulator, collimator, and/or optical coupler, projector, and/or direct laser scanning into or onto the retina. One, two, or more white LEDs can be utilized within a light engine.

In certain embodiments, the focal length of a projector or display used within a light engine of the AR Unit can be altered by moving the focusing lens closer to the projector or further away. The movement can be by way of MEMs system and/or a micro motor. The movement can be automatically, semi-automatically, or manually controlled. In certain embodiments, the illumination source illuminates the micro display, light from which is collected, focused and transmitted into a fiber optic delivery system or a waveguide. The micro-display forms the virtual image to be projected at a desired distance from the eye of the wearer. The fiber optic, waveguide, or lightguide delivery system can carry the AR image information to the combiner which is then directed to the pupil. In certain embodiments, a fiber optic delivery system may comprise a plurality of optical fibers that end in a second optical coupling device which may comprise a prism and/or a combination of, by way of example only, a lens and a prism, or a stack of partially transmissive thin layer films. The waveguide or lightguide delivery system may end in a second optical coupling device which may comprise a prism and/or a combination of, by way of example only, a lens and a prism, or a stack of partially transmissive thin layer films. The optical coupling can include an optical grating. In certain embodiments, a single projector with a beamsplitter can illuminate two optical windows.

In certain embodiments, the optical combiner combines light emanating from the projector carrying an AR image information with light coming from real objects that the wearer is looking at and thereby enables the AR virtual image to be located at a distance, by way of example only, from 40 centimeters to 6 meters in the real environment. The AR Unit can be designed to combine and align the wearer's convergence and accommodation for that of a virtual image seen by the wearer with that of a real image seen by the wearer.

The AR Unit can support one or multiple cameras. In certain cases, when multiple cameras are utilized, they can be spaced to provide for an increased 3D effect. In other cases, when multiple cameras are utilized, they can be utilized for spatial location. When multiple cameras are used they can be distance separated from one another. When multiple cameras are utilized, one can be located at or near the horizontal center of AR Unit's main body and the other attached to a temple of the eyewear or located on or near one of the horizontal ends of the AR Unit's main body. (See, e.g., FIGS. 53-54.) When one camera is utilized the camera can be located at approximately the horizontal center of the AR Unit main body. One or more of the cameras can be capable of capturing one or both of a still image and video.

The AR Unit may comprise a power source, including an energy harvesting power source. In certain embodiments, the AR Unit can be attached to and detached from a solar power or other power unit. In certain aspects, the AR Unit may connect to a visor or other structure, whereby the visor harvests solar energy. Such a visor or other structure can comprise a plurality of solar cells.

In certain embodiments, the AR Unit comprises an electrical tether that fits around the head, behind, the head, behind the neck, or around the neck, of a wearer. (See, e.g., FIGS. 28-30.) The electronic tether can have two strands 2810; one that comes from the right side of the AR Unit and one that comes from the left side of the AR Unit. The electronic tether can be electrically connecting to the AR Main Unit body. The electronic tether can comprise one or more electronic modules. Electronic components can be attached to or included in all or a portion of the tether or the modules. By way of example only, the electrical tether may be attached to a battery 2820. The battery can be a rechargeable battery. The battery can be recharged by a wired connection or by wireless power.

The electronic tether and electrically connected electronics module can house, support, or be connected to one or more of the following electronic components, by way of example only: memory storage, flash memory, random access memory, EEPROMs, an electrical power unit, such as a battery or rechargeable battery, earbud, assisted hearing device, wife chip, Bluetooth chip, vibrator, communication system, antenna, audio system, GPS, sensor, ASIC, CPU, controller, switch, transceiver, transmitter, receiver, and/or an auditory system. The electronic components can be housed within a module that is connected or supported by the electrical tether. The module can be sweat resistant and water resistant. The module can be sweat proof and water proof.

The AR Unit can comprise an auditory system. The auditory system can utilize ear buds. The ear buds can be connected by a wired connection to the AR Unit. When wired to the AR Unit, the ear buds connect in most but not all cases to the electronic tether. The ear buds can be wirelessly connected to the AR Unit. The auditory system can utilize bone conduction for audio transmission. A personal assistant can be part of the auditory system.

The AR Unit can connect to and disconnect from, wirelessly or by a wire, one of, by way of example only, a smart phone, computer device, tablet, laptop, or computer processing unit.

The AR Unit, when attached to an eyewear frame being worn by a wearer, can be capable of being positioned above the head of a wearer. In aspects, the AR Unit can be positioned on top of an eyewear frame front when in use and worn above or below the head of the wearer when not in use or when detached from the eyewear frame. In certain embodiments, the AR Unit main body provides for a recess on its bottom side that accepts the top of an eyewear frame front. In certain embodiments, a pin or pins can connect the AR Unit main body to a compressible material. The compressible material can be attachable or attached to the AR unit main body. The compressible material can be available in multiple sizes, compression factor, and a variety of colors. The compressible material can be one of, by way of example, sponge, sponge-like, foam, or foam-like. In certain embodiments, the compressible material can be utilized when there is an open space between the top of the eyewear frame front and the bottom of the AR Unit. When a compressible material is used to fill such an open space, the compressible material attaches to the bottom of the AR Unit's main body and the top of the eyewear frame front. In certain embodiments, a façade is utilized to fit under the bottom of the AR Unit's main body and above the top of the eyewear frame front above the eyewear bridge. The façade fills in an opening above the bride of the eyewear frame and beneath the bottom of the AR Unit's main body. Such a façade can be held in place either by, by way of example only, one or more of a pressure fit, mechanical attachment, or structural attachment.

In certain embodiments, the AR Unit's main body includes a horizontal slit aperture in which an optical window is attached to, transcends through, and/or descends from. In other embodiments, the optical window(s) do not include or need horizontal slit(s). The AR Unit can have two horizontal slit apertures to which two optical windows transcend. The horizontal slit aperture, in aspects, can be longer horizontally than that of the width of the top of an optical window. This permits the optical window to be adjusted horizontally to align the optical combiner with the pupillary distance of the wearer's eyes. When the optical window is located in front of the eyewear frame, the horizontal slit(s) can be located in the portion of the AR Unit's main body that overhangs in front of the eyewear frame (further from the head of the wearer). When the optical window is located behind the eyewear frame, the horizontal slit(s) can be located in the portion of the AR Unit's main body that extends behind the frame closest to the head of the wearer. And when the optical window is located in the lens of the eyeglass frame, the slits can be located above the eyewear frame.

The AR Unit may comprise an optical coupler, which can be used to couple one of a lightpipe, optical fiber, or micro-display to that of the optical window. An optical coupler can be used to couple a micro-display to one of an optical window, lightpipe, or optical fiber. An optical coupler can be used to couple a lightpipe or an optical fiber to an optical combiner. An optical coupler can be used to optically couple a waveguide to a light engine or light source. An optical coupler can be used to optically couple a lightguide to a light engine or light source. In certain embodiments, as used herein, lightpipe, waveguide, and lightguide refer to an underlying mechanism to perform the same or substantially the same function; namely, to transmit or otherwise transport light from a display to the eye of a wearer of the apparatus (e.g., in certain embodiments to transmit light from the light engine to the eye of the wearer by way of the light engine).

In certain embodiments, the bottom of the optical combiner can be angled away from the eye. In aspects, the bottom of the combiner can be angled away from the eye such that the line of sight of the user is perpendicular to the combiner when his or her chin is tilted down and when looking straight ahead. By way of example only (see e.g., FIG. 55) the optical window/optical combiner 5510 can be tilted with its bottom away from the eyeglass lens so that the line of sight of the wearer with head tilted and looking straight ahead is looking perpendicular thru the optical combiner. In other embodiments, the bottom edge of the optical combiner is not tilted away from the front of the eyeglass lens.

In certain embodiments, the AR Unit can include an eye tracking system. Such systems are known in the art. The image generated by the light engine(s) and or optical engine(s) can be controlled to move in concert with that of the eye(s) of the wearer, as located by the eye tracking system.

In certain embodiments, such as those in FIGS. 38-39, the AR Unit comprises one or more of eight parts: 1) The main body of the AR Unit 3960, which is located above the top of an eyewear frame, 2) certain optical engine components 3840, 3850, 3940, 3950 that provide and cause the virtual image to be merged with a real image, 3) certain light engine components 3830, 3930 that generates the virtual image, 4) a connector means (not shown) that supports and connects the AR Unit to the eyewear frame, 5) an electronic tether 3970 that connects the main AR unit to that of an electronic module worn on about the head or mostly behind the neck of the wearer, 6) an electronic module, which is part of the electronic tether located behind the head or neck of a wearer, and which comprises multiple electronic components as well as the major battery/power supply for the AR unit, 7) electronic components (not shown but certain of which are listed herein) that are located within the AR Unit main body 3960 (these components can be compartmentalized and housed in one or more modules) and/or 8) an image capture system 3820, 3920.

The electronic module of #6 above may also include, by way of example only, one or more of facial recognition, a GPS system, a sensor, a UV Sensor, an electro mechanical sensor, a mechanical sensor, a pressure sensor, a temperature sensor, an accelerometer, a communication system, a pedometer, an audio system, an image processor, a BlueTooth chip, a wifi chip, a BlueBooth system, a wifi system, a solar cell, a gas sensor, an air quality sensor, a vibrator, a buzzer, a speaker, a microphone, an activity tracker, a radiation sensor, a time clock, a voice recognition system, an intelligent personal assistant system, an intelligent virtual assistant system, a geo location system, and/or a GPS system.

The light engine of #3 above may comprise one or more of, by way of example only, a display unit(s) and/or projector(s) 3830, 3930, electronic displays, such as LCD, micro OLED or micro LED (μLEDs), LED display, OLED display, see-through OLED display, TOLED, DLPs, LCOS, as well as scanning display types such as a vibrating fiber, laser scanning display, laser-based projector, a lenticular (based on micro-lens arrays), focusing lens, spatial modulator, collimator, and/or optical coupler, projector, and/or direct laser scanning into or onto the retina, focusing lens(es), collimator(s), microlens array(s), optical coupler(s), diffractive optic(s), spherical lens(es), aspheric lens(es), prism(s), mirror(s), reflector(s), optical combiner(s), focusing optic(s), tunable optic(s), magnifying optic(s), de-magnifying optic(s), and/or optical grating(s), collimator(s), and/or optical coupler(s).

The optical engine of #2 above can comprise one or more of the following: waveguide(s), waveguide array(s), lightguide(s), mirror(s), lens(es), optic(s), collimator(s), microlens array(s), optical coupler(s), grating(s), optical fiber(s), lightpipe(s), reflective element(s), beam splitter(s), Pupil Relay(s), segmented reflector(s), Fresnel or diffractive facet(s), optical combiner(s), combiner(s), coating(s), diffractive element(s), optical window(s), and/or optical substrate(s). The optical engine can also comprise focusing lens(es), optical coupler(s), diffractive optic(s), spherical lens(es), aspheric lens(es), prism(s), mirror(s), reflector(s), optical combiner(s), see-through OLED display, focusing optic(s), tunable optic(s), magnifying optic(s), de-magnifying optic(s), optical grating(s), collimator(s), and/or optical coupler(s).

Certain component(s) of the optical engine can provide pupil multiplication. In most embodiments disclosed herein, one or more of the optical window or optical combiner is that of a top down member. By way of example only, one or more of the waveguide, lightguide, optical window, and/or optical combiner, can be attached to the AR Unit's main body located above the eyewear frame, thus providing for a top down optical combiner or optical window when attached to the AR Unit's main body and located in front of the pupil of the wearer when an augmented reality image is viewed by the wearer. In other embodiments, the optical combiner can be attached to the side and come across from a side of the AR Unit's main body.

The image capture system or #8 above can capture photos and HD videos. The image capture system can be a camera. A courtesy light can be located on the AR Unit to inform an individual whose image is being captured that such an action is occurring. A courtesy light can be located near or adjacent to the image capture system of the AR Unit. However, it should be noted that a courtesy light can be located anywhere on the AR unit such to provide a front facing light. In some cases, a second camera can be attached to the temple and/or to the AR Unit, as shown in, for example, FIGS. 53-54.

In certain embodiments, the optical window(s) can be located in front of the lens, further away from the eye (see, e.g., FIGS. 25, 38). In other embodiments, the optical window(s) can be located behind the spectacle lens closest to the eye (see, e.g., FIG. 24). In still other embodiments, the lens of the eyewear acts as an optical window and includes an optical combiner. In this case, the optical combiner can be, by way of example only, a reflector or mirror. Such a reflector or mirror can comprise optical power to reduce aberrations.

When the optical window is located behind the spectacle lens closest to the eye or incorporated in the spectacle lens, a tunable lens is required to properly align the wearer's accommodation and convergence with that of the virtual and real images. In certain embodiments where the spectacle lens is that of a filler lens having no optical power, a tunable lens is not required. In certain embodiments this can be accomplished by mechanically moving a focusing lens closer or further from the projector or display. When a tunable lens is utilized, such tunable lenses are known in the art.

In certain embodiments, the spectacle lens of the eyewear acts as the optical window and/or the optical combiner. In these embodiments, the optical window/optical combiner is not moveable, and the optical combiner must be aligned to the pupil of the wearer. As stated earlier, in certain embodiments, a reflecting material properly aligned acts as an optical combiner. Such a reflective material can be on a surface (inner or outer convex or concave) of the lens or embedded within the lens matrix. When this occurs, the optical combiner can be properly positioned relative to the pupil of the wearer when the lens is edged for the shape of the eyeglass frame and inserted into the eyeglass frame. The optical combiner may be located by way of example only, in the lens in front of the pupil of the eye of the wearer, in the lens above the pupil of the eye of the wearer, and/or in the lens above the line of sight of the wearer. Both lenses of the eyewear can each comprise one optical combiner. When a lens or two lenses are used as the optical window/optical combiner, the image being optically communicated can be transmitted from the top edge of the lens thru the lens to the optical combiner which can be incorporated therein or in other embodiments located on the surface of the lens. The image being optically communicated can be projected at the required location on the top edge of the lens so that it is incident on the optical combiner within or on the lens. The top edge of the lens can comprise an optical coupler that transmits the optically communicated image. The optically communicated image can be the augmented reality image or the virtual image that is seen by the wearer of the AR Unit. The upper rim of the eyewear frame front that houses a lens can comprise an aperture to allow the optically communicated image (e.g., projected image) to be transmitted through the eye frame rim, as shown in FIG. 41. This aperture of the eyewear frame can be formed as an oval or rectangle having its longest dimension horizontally along a length of the top eye frame rim of the eyewear frame. This aperture 4100 allows for the optically communicated image to pass through the frame eye rim and be communicated to the lens (optical window). In another embodiment, the edge of the lens is formed with a protrusion on the lens itself, near or adjacent to its edge, such that the optically communicated image can be communicated without the frame eye rim interfering. In aspects, when both lenses are used as optical windows comprising optical combiners, the top of each eye frame rim that houses each of the lenses will have an aperture formed therein. In some embodiments, an optical coupler is used to connect the optic transmitting the optically communicated image to the top edge of the lens. In aspects, the optic transmitting the optically communicated image is positioned adjacent to, but not bonded to, the top edge of the lens. The top edge of the lens can be shaped to be flat or of any topography that will best transmit the optically communicated image. In a different embodiment, the edge of the lens is formed with a protrusion of the lens itself such that the optically communicated image can be communicated by the communicating optic without the eye frame rim interfering. The communicating optic can be coupled to the protrusion near or adjacent to the edge of the lens. The communicating optic can be bonded to the protrusion near or adjacent to the edge of the lens. The communicating optic can be placed adjacent to the protrusion near the edge of the lens. The protrusion near the edge of the lens can be polished.

In still other embodiments, as shown in for example, FIGS. 50-52, an optical grating 5010, 5110, 5210 is used to optically communicate the image from the light engine (e.g., projector or display) to an optical combiner via a waveguide 5020, 5120, 5220. In embodiments, the AR Unit main body includes one waveguide optical combiner of the optical window for monocular use or two for binocular use. In FIGS. 38 (front view)-39 (top view), a waveguide optical combiner and optical window are depicted as 3850, 3950. The vertical height of the waveguide optical combiner of the optical window is adjustable by way of edging the waveguide optical combiner of the optical window to the desired vertical height for a given frame eye size and style relative to the wearer's pupil. The optical combiner or optical window can be located with its bottom edge at or above the top edge of the pupil(s) of the eye(s) of the wearer. The optical combiner or optical window can be located with its bottom edge at or below the lower edge of the pupil(s) of the eye(s) of the wearer. The displayed augmented reality image can be programed to be displayed in relation to the usable waveguide optical combiner/optical window dimensions (vertical height and horizontal width). In embodiments, the bottom edge of the waveguide optical combiner of the optical window can be set above the top edge of the pupil 5140 as shown in, for example, FIG. 51. At 5140 is where the pupils are located when the wearer is looking straight ahead; 5150 is where pupils would be when the user tilts the head forward, for example. Alternatively, in FIG. 52, an embodiment is shown wherein the optical combiners make up the full optical window(s). In this embodiment, the optical window(s) are of a vertical height so that they cover the wearer's pupils even when looking straight ahead without the head tilted 5240. The waveguide optical combiners/optical windows can be positioned in front of, behind the spectacle lens(es) of the wearer, or embedded within the spectacle lens(es) of the wearer. But in a preferred embodiment, they are positioned in front of the spectacle lens(es) of the wearer furthest from the eyes of the wearer.

The AR Unit can be water proof. The AR Unit can be water resistant. The AR Unit can be sweat proof. The AR Unit can be sweat resistant.

In certain embodiments, the AR Unit can project a virtual image at one or more of: a near, intermediate, or far distance. The AR Unit can adjust the location of the virtual image and its magnification so that the convergence of the wearer's eye viewing the virtual image is consistent with the accommodative stimulus experienced by the eye. The AR Unit can align the location of the virtual image, so the accommodation and convergence of the wearer's eyes are aligned with the real image. The AR Unit can equalize the magnification seen by the wearer of the virtual image and the real image when combined.

In certain embodiments, the AR Unit can adjust the focus and magnification of the virtual image anywhere within the field of view in order to allow for the wearer's convergence at any point of regard. In certain embodiments, the AR Unit's projection system can alter its focus for different distances. This can be accomplished with a tunable lens or a tunable optical system. Such lenses or systems are known in the art.

Regarding eyewear frames, the AR Unit main body fits on eyewear having prescription lenses or a pair of eyewear having non-prescription lenses. The spectacle lenses can be single vision, multifocal, trifocals, and/or progressive addition lenses. The spectacle lenses can have optical power or no optical power. The spectacle lenses can be tinted or clear. The AR Unit main body can fit on an eyewear frame having no lenses. The AR Unit's main body itself may comprise one or more ophthalmic lens. The eyewear on which the AR unit's main body fits and/or attaches can be that of any eyewear, by way of example only, one of: sports, shooting, swimming, safety, industrial, welding, enterprise, dress, fashion, sunglass, space, and/or goggles. The eyewear can be, by way of example only, one of: wire frames, plastic frames, and/or a combination of wire and plastic frames. The AR Unit can be releasably attached to the eyewear on which it rests. In certain embodiments, the AR Unit is releasably attachable to the eyewear frame and the optical window is part of the AR Unit. In other embodiments, the AR Unit is releasably attachable to the eyewear frame and the optical window is part of the eyewear. When the optical window is part of the eyewear frame, it can be embedded within the eyewear lens(es), in front of the eyewear lens and attached to the frame front, or behind the eyewear lens and attached to the frame front. When the optical window is part of the frame front it will limit the available selection of eyewear styles available to the consumer having such a feature.

In preferred embodiments, the AR Unit's main body comprises one or more flex joint allowing for the AR Unit to better conform to the shape of an eyewear frame. A portion of the AR Unit's main body may be made from a flexible material. A portion of the AR Unit's main body can be made by way of example only, a urethane material. As shown in FIGS. 23-25 and 43, the AR Unit's main body 2300 can comprise one or more internal rigid electronic module 2310, 2410, 2510. In certain embodiments, multiple rigid separated electronic modules can be utilized within the AR Unit's main body. These multiple electronic modules can be connected by a member whereby the member permits one module to be rotated or flexed away from or closer to the other. The AR Unit's main body can comprise a rigid electronic module embedded within a flexible outer body covering of the AR Unit's main body. The rigid electronic module can have one or multiple flex joints (see, e.g., FIG. 43). The rigid electronic module can be partially or fully embedded in the AR Unit's main body. As shown in FIG. 26, the module 2610 may have, for example, conformable wing structures, such that the electronic module comprises one or more conformable or bendable portion. In aspects, two portions to the right and left of the module 2640 can be bent to conform to a shape complimentary with the eyeglass frame front on which the AR Unit's main body rests and/or electronic module rest. As shown in FIG. 27, in another embodiment, the electronic module 2710, may comprise a single conformable member 2750, which may be bent to conform to a shape complimentary with the eyeglass frame front on which the AR Unit's main body rests. The flexible AR Unit's main body can have a groove located in the bottom edge of the AR Unit's main body for receiving a portion of the top edge of an eyewear frame. The AR Unit′ main body can have a groove for receiving a connector member on the top outer surface of the AR Unit's main body. The AR Unit's main body can have multiple grooves for receiving a connector member on the top outer surface of the AR Unit's main body. The AR Unit's main body can contain one or more magnet, ferromagnetic material, and/or an aperture. The AR unit's main body can rest upon the top of the eyewear frame front (as shown, e.g., at 2420, 2520) and be connected to one or both eyewear temples 3970. The AR Unit's main body can be connected to an eyewear temple. The AR Unit's main body can be connected to two eyewear temples 2330, 2430, 2530. (See, e.g., FIGS. 23-25.) The AR Unit's main body can be connected to the eyewear frame front. The connection to the eyewear frame front can be by way of a connection member, by way of example only: a strap, loop, ring, fastener, clip, and/or magnetic attachment. The strap, loop, ring, or fastener can be adjustable and/or elastic.

When connected to the frame front, the connection can be by way of example only, the eyewear rim, bridge, and/or temple region of the frame. The connection to the eyewear temple can be at the bottom of the eyewear temple, the top of the eyewear temple, the inside of the eyewear temple, the outside of the eyewear temple, around the eyewear temple, and/or on a side of the eyewear temple. The connection to the eyewear temple can be attached to a track, groove or male feature designed into the side of the eyewear temple.

In still other embodiments, the solar visor mechanically attaches to the AR Unit's main body only. In certain embodiments, the solar visor magnetically attaches to the eyewear frame. In other embodiments the solar visor magnetically attaches to the eyewear frame and/or the AR Unit's main body. In other embodiments, the solar visor magnetically attaches to the AR Unit's main body only. In still other embodiments, a solar harvesting member is attached and electrically connected to the electronic tether of the AR Unit and is worn by the wearer around the neck and shoulders of the wearer. In still other embodiments, a solar harvesting member is attached and electrically connected to the electronic tether of the AR unit and is worn on the head of the wearer, by way of example only, a cap, hat, or visor.

Eyewear comes in hundreds, if not thousands, of different styles, shapes, sizes and materials. (See, e.g., FIGS. 5-6.) For the purposes of minimizing the number or AR Unit main body SKUs (stock keeping units) and to allow the AR Unit's main body to look fashionable when applied to the eyewear frame, the AR Unit can comprise, by way of example only, one or more of a compressible and/or formable material. In certain embodiments, the AR Unit's main body will fit on the eyewear frame front. In other embodiments, the compressible material above the eyewear bridge and/or affixed to or embedded in the bottom area of the AR Unit's main body is preferred or necessary for proper fit. Because of the current invention's ability to fit many types of eyewear frames, one SKU (stock keeping unit) of a design of the AR Unit's main body can be optimized to fit a plurality of different eyewear shapes and sizes. (See, e.g., FIGS. 7, 45-48.) A separate part can be attached to the one SKU design to enhance the cosmetic appearance and/or fit of the AR Unit's main body attached to certain eyewear shapes, if necessary. The separate part can be a façade that is utilized to cover open space formed when the AR Unit's main body is fitted upon the top of the eyewear frame front. In most but not all cases, a façade is utilized between certain locations under the AR Unit's main body and above the top of the frame front. By way of example only, a façade can be used to fit beneath the bottom of the AR Unit main body and the top of the eyewear frame front superior to the bridge area. In still other cases, multiple facades can be used to cover up multiple openings formed under the AR Unit's main body and superior to the top of the eyewear frame front. The separate part can be offered as multiple separate parts (or facades) of different sizes or shapes to the consumer thus allowing for further improved fit and/or cosmetic enhancement of the AR Unit's main body for even a larger number of different eyewear shapes and sizes. In certain embodiments a kit of facades are included with the sale of the AR Unit. The separate part can be rigid, compressible, or conformable, depending on the spatial relationship of the bottom of the AR Unit's main body and the top of the eyewear frame located above the bridge of the eyewear front. The invention disclosed herein allows for one AR Unit's main body to fit a plurality of different eyewear styles and sizes, allowing a limited number of different AR Unit main body shapes to fit a majority of eyewear styles and sizes. The invention disclosed herein allows for a limited number of different AR Unit main bodies utilizing one or more of a compressible material, façade, flexible structure of the AR Unit's main body, and/or shapeable portions of the AR Unit's main body such as (by way of example only) the outer AR Unit's main body covering, to fit the majority of eyewear styles and sizes. For example, the invention disclosed herein allows for five or fewer different AR Units utilizing one or more of a compressible material, façade, flexible structure of the AR Unit's main body, and/or shapeable portions of the AR Unit's main body such as (by way of example only) the outer AR Unit's main body covering, to fit the majority of eyewear styles and sizes. In cases, no compressible material will be needed for adequate attachment to the eyewear frames. (See, e.g., FIG. 12.) In aspects, a portion of the augmented reality device is flexible, whereby a bendable member is housed within or attached to the flexible portion and whereby the flexible portion of the augmented reality device supporting a bendable member rests on top of an eyewear frame front. It should be pointed out, that certain embodiments of the AR Unit invention disclosed herein can be flexible and others are not flexible but can be rigid.

In certain embodiments, the AR Unit has all or part of its memory and/or computational requirements off loaded from the AR Unit to that of a remote and/or mobile device. By way of example only, a cell phone or smart phone case, a smart mobile unit, or a CPU, supports or includes remote memory and a CPU for the AR Unit, whereby the remote memory and/or CPU communicates with the AR Unit wirelessly or by wire. In embodiments, the cell phone case or smart mobile unit, or CPU, would comprise the necessary electrical components required to provide such wireless or wired communication, memory storage and/or retrieval, and remote computation.

As shown in FIGS. 34-37, in certain embodiments, a separate part 3410, 3510, 3610 which acts as a facade can be attached to the AR Unit's main body as illustrated herein when needed (see also, e.g., FIGS. 10 and 45-48). The separate part acts as a façade covering the open space (hole) 3420, 3520, 3620 over the eyewear bridge 3430, 3530, 3630. In one embodiment of the invention, multiple separate parts would be included as a kit when the AR Unit is sold (see, e.g., FIG. 37). In certain other embodiments, one manually adjustable pull-down member found within the AR Unit's main body can be used to cover an open space above the bridge of the eyewear and beneath the middle of the AR device when the augmented reality device is positioned on the top of the eyewear front. (See, e.g., FIG. 40.) By incorporating one pull down member within the bottom of the AR Unit's main body, it acts as a façade covering an open space that will appear when an AR Unit's main body is attached to different sizes or different eyewear frame styles. The middle member can be pulled down further to cover a larger open space or less far to cover a smaller open space. When a pull-down member is utilized as a façade, it is integral with that of a portion of the AR Unit's main body. When a separate part is utilized, it can be part of a kit of separate façade parts. The separate facade parts can be attached to the AR Unit's main body to cover the open space above the bridge of the eyewear frame from which the AR Unit rests upon. The separate façade part can be attached to the AR Unit's main body by way of example only, a pressure connection, slide in connection, magnetic connection, mechanical joint, or male-female mechanical connection.

As shown in FIGS. 46-48, in one embodiment, the AR Unit's main body can have a dividing line 4600, 4700, 4800 that separates the right half from the left half. The dividing line allows for the right half to be flexed or rotated from the left half, or vice versa. (See, e.g., FIGS. 46-48; see also FIG. 51.) The degree of rotation or flex can be, in aspects, within the range of 0.5 degrees to 25 degrees. A preferred range is between 5 degrees and 15 degrees. In a preferred embodiment, the “total” degree of rotation or flex is 10 degrees relative to one another (either half). When the AR Unit is flexed in the middle, one or both optical windows can be rotated clockwise or counter clockwise, or otherwise adjusted, to remain properly aligned to receive and display an AR image to the wearer as described herein. In certain embodiments, the right half and the left half remain attached and rotate or flex by way of a mechanical member, hinge, formable member, and/or joint. In still other embodiments, the right half and the left half are totally separated and are two distinct parts.

As shown in FIG. 49, the AR Unit's main body may be raised and lowered above the eyewear frame front to which it is resting upon. This can occur, for example, by way of any known mechanical means such as a set screw(s) 4910. This allows one or more of the wearer, technician, seller, or optician to adjust the AR Unit's main body up and down such to align the optical window and/or the optical combiner to be positioned as desired in relation to the line of sight of the wearer, or in relation to a pupil(s) of the wearer. An optical window and/or optical combiner can be moved independently of the AR Unit's main body and/or camera 4930. An optical window and/or optical combiner can be moved as the AR Unit's main body and/or camera is moved 4920. An optical window or optical combiner can be moved by way of example only, one or more of counterclockwise, clockwise, along the X axis, along the Z axis, and/or along the Y axis.

In certain embodiments, a tap (or series of taps) of the AR Unit's main body, eyeglass frame, or more specifically an eyeglass temple, can turn on and/or off the AR Unit. In certain embodiments, a tap (or series of taps) of the AR Unit, eyeglass frame, or more specifically an eyeglass temple, captures an image or video image with a camera or cameras, or image capture device that is associated with the AR Unit. (In certain embodiments, the camera may be spring-loaded (see, e.g., FIG. 11).) In other embodiments, the camera is located stationary with the AR Unit's main body. In aspects, a voice command turns on or off the AR Unit. In aspects, a voice command triggers a camera or cameras that is associated with the AR Unit to capture an image or video. In aspects, a blink of an eye(s) by the wearer turns on or off the AR Unit, or triggers a camera that is associated with the AR Unit to capture an image or video. In aspects, a jerk or movement of the head turns on or off the AR Unit. The electrical tether or AR Unit's main body may comprise a capacitive switch which allows for, by way of example only, a swipe to turn the AR Unit on and, for example, an opposite swipe to turn the AR Unit off. In certain embodiments, a tilt switch can turn the AR Unit on or off. When the head is looking straight ahead without the wearer's head tilted, the tilt switch can turn the unit off. However, when the wearer's chin is tilted down the AR unit can turn itself on. The AR Unit can use AI (artificial intelligence) to learn to differentiate between when the wearer desires to see AR and when the wearer is just looking down by tilting his or her head. Feedback for the wearer on the status of the AR Unit or camera may be provided by a vibrator, buzzer, bell, light, personal assistant, acoustic system, or other ways of communicating with the wearer.

Also, all embodiments disclosed herein are enabled with the appropriate electronic components including electrical power and circuitry, which are known in the industry and by those of ordinary skill in the art.

The see-through OLED optical combiner can be a side mounted optical combiner, meaning it comes across from a horizontal side of the lens or from the temple of the eyewear frame across the lens. The see-through OLED optical combiner can be a top mounted optical combiner, meaning it comes from the top of the lens down.

Such a curve can be like the base curve of such eyeglass lens. The see-through OLED micro-lens array optical combiner can be curved in a similar manner as the front surface of the eyeglass lens to which it is in front of. Such a curve can be like the base curve of such eyeglass lens. In most embodiments, but not all, the curved see-through OLED is of a spherical curve. However, in certain other embodiments, the curved see-through OLED can be of an aspheric curve.

By way of example only, the following can be base curves for an eyeglass lens having a specific power.

Sphere Power Base Curve >+12.25 +16.00 D +10.75 to +12.25 +14.00 D  +9.00 to +10.50 +12.00 D +5.50 to +8.75 +10.00 D +2.25 to +5.25  +8.00 D −1.75 to +2.00  +6.00 D −2.00 to −4.50  +4.00 D −4.75 to −8.00  +2.00 D −8.00 to −9.00  +0.50 D <−9.00  plano or minus

When manufacturing the see-through OLED curved to that of approximating the base curve of the spectacle lens, one or two SKUs of OLEDs can be manufactured in volume. These one or two SKUs can first be fabricated either in a flat profile or a curved profile and then bent to the curve required for the eyeglass lens or eyewear lens with which they will be in optical communication. Due to distribution of eyewear prescriptions, five different curvatures, for example, can accommodate 90% of all eyewear prescriptions and nine different curvatures, for example, can accommodate 95+% of all eyewear prescriptions including that of plano (no optical power). This manufacturing method is important when the see-through OLED is applied to an optical window or optical substrate to be utilized as an optical window.

In certain embodiments, a semi-transparent OLED display supported by an optical window may be mounted on the inside or the outside surface of the optical window (as disclosed herein) and may be used to project augmented reality content onto the pupil. In certain embodiments, the OLED display can be the optical window. Such a semi-transparent display may be a see-through OLED that comprises a RGB stack and that is driven by a graphic processing unit. The semi-transparent OLED display compares with other display technologies in terms of brightness, field of view, and energy consumption (see, e.g., FIG. 60).

The see-through display may be mounted permanently on the AR device, or it may be mounted on an optical window. (See, e.g., FIG. 2.) It may take the place of the optical window such that it is enabled to be moved upwards or downwards, or it may be attached to an optical window that enables it to be rotated away when the AR device is not in use. (See, e.g., FIG. 29, 2920.) Accordingly, in aspects, the optical window(s) may be moved up and out temporally when the AR Unit or system is not being used. Alternatively, the optical window(s) can be left in a working position when the AR Unit or system is not being used and the optical window(s) can be raised vertically when the AR Unit or system is not being used. Preferably, the display pivots on its distal end, near the eyeglass frame hinge, and the rotation can take place either in the x,z or x,y planes. (For example, see, e.g., FIG. 22.)

It may take the place of the optical window such that it is enabled to be moved upwards or downwards, or it may be attached to an optical window that enables it to be rotated away when the AR device is not in use. (See, e.g., FIG. 29, 2920.) Accordingly, in aspects, the optical window(s) may be moved up and out temporally when the AR Unit or system is not being used. Alternatively, the optical window(s) can be left in a working position when the AR Unit or system is not being used and the optical window(s) can be raised vertically when the AR Unit or system is not being used. Preferably, the display pivots on its distal end, near the eyeglass frame hinge, and the rotation can take place either in the x,z or x,y planes. (For example, see, e.g., FIG. 22.)

The pixel size of the see-through OLED display may be in the range of 1.5-10 microns, preferably 2-3 microns. This display can be 4000×3000 pixels. The minimum pixel count is preferred to be 1×106 pixels. The upper limit of the pixel count is determined by the amount of power required to operate the display. Since OLEDS are current driven (they operate mostly between 2-4 volts), the maximum power of the display unit (for each eye) is 750 milliwatts, or about 1.5 watt for both displays, in aspects.

Use of a see-through OLED in the display also may serve to increase the field of view of the AR image. For example, a field of view of up to 100 degrees (e.g., a range of 50-100 degrees) is possible. The binocular field of view of natural vision is about 110 degrees.

In a certain embodiment, a see-through OLED stack is used, as deposited on a transparent plastic film with barrier properties such as polyimide. The OLED stack is encapsulated in between two layers of flexible transparent plastic films for durability. The encapsulated stack may be further mounted on an optical window of the AR Unit's main body as taught herein. This plastic sheet may constitute an additional layer, or it may the same layer as the substrate. (See, e.g., FIG. 4 for a possible layered embodiment.) If one display is utilized, it may be monocular. If two displays are used, it may be binocular. The optical window(s) may be transparent or partially transparent. It may be coated with antireflective coatings. It may be photochromic, electrochromic, or thermochromic. In these embodiments, the optical window(s) can be darkened in environments with high ambient illumination in order to equalize the relative brightness of the real and the virtual images and lightened in other lighting environments where this is not needed.

When see-through OLED display(s) are utilized as the optical combiner(s), the AR Unit's main body can be reduced in size and weight. This is due to the fact that the number of components utilized in the light engine(s) and optical engine(s) can be reduced. In addition, in many cases the energy requirements of the AR Unit can also be reduced. (See, e.g., FIG. 3.)

When the optical combiner is a see-through OLED display(s) or the AR Unit utilizes a see-through OLED display(s), the see-through OLED display is capable of being used for, or as a component for, XR, AR, Virtual Reality, and/or Mixed Reality.

Turning to a few figures, regarding FIG. 58, in a preferred embodiment, the semitransparent OLED stack is curved in a shape conformal to the eyeglass optics and is equal to or less than the area of the eyeglass optic and mounted on the eyeglass frame outside the eyeglass optic. In this position it forms the virtual image and projects it at infinity and thereby functions as a combiner. In a preferred embodiment, the semi-transparent OLED or see-through OLED may be shaped to conform with the outer curve of the lenses providing refractive correction. For this purpose, the substrate used for the semi-transparent OLED may be a thin, flexible transparent ceramic or glass, or a plastic film. Preferably the glass may be float glass. In one embodiment, the OLED stack may comprise an electrode layer that has been reinforced with a mesh made of a metal nanowire in order to improve transparency of the electrode layer and enhance its flexibility, enabling the semi-transparent OLED to be bent to a shape conformal to the eyeglass optic providing refractive correction.

The see-though OLED optical combiner can be made of flexible OLEDs using a mechanically robust Ag mesh/ITO composite electrode and micro-lens array. Regarding FIG. 59, MLA is microlens array and Ag mesh is mesh made of silver nanowire. (See Shin, S-R, et al., “Improving light extraction of flexible OLEDs using a mechanically robust Ag mesh/ITO composite electrode and microlens array.” in J. Mater. Chem., 2018, 6, p. 5444). The enhancement factor caused by the addition of a layer of a microlens array was reported to be 1.55 in the aforementioned Shin article.

Regarding FIG. 60, this is an example of an electrode layer powering a semi-transparent OLED reinforced with a mesh made of silver nanowires. Light emitted by the OLED stack is nearly Lambertian; in other words, it is emitted equally in all directions. In certain embodiments, the brightness of the virtual image created by the see-through display as perceived by the retina can be enhanced by providing a layer of transparent plastic with micro-lenses of the same size as the pixels in the OLED that collect and collimate the emitted beam. In certain embodiments, a microlens array may be incorporated as an additional layer in the OLED stack. The microlens array is readily formed by molding using a soft mold made of PDMS (polydimethyl siloxane), and combined with a transparent electrode such as an ITO electrode or an ITO electrode reinforced with a mesh made of silver nanowires. FIG. 60 also shows the improvement in mechanical flexibility of the OLED stack caused by introduction of metal nanowire reinforcement. In certain embodiments, the micro-lens array (or micro-optic array) can be a switchable micro-lens array (or micro-optic array). In other embodiments, the micro-lens array (or micro-optic array) can be a static micro-lens array (or micro-optic array).

Regarding FIG. 61, it shows normalized luminance of ITO- and Ag mesh/ITO-based OLEDs versus (a) bending radius and (b) bending cycles.

FIG. 62 shows that image intensity and image contrast of the virtual image may be further enhanced by adding a switchable optical shutter rendering the spaces in which the virtual image is black more perfectly black. In a preferred embodiment, a switchable dynamic optical shutter is added as an extra layer in the OLED stack, facing outwards. The shutter is pixilated and each pixel in the shutter can be addressed individually. The shutter is activated to cut off ambient illumination from being incident on the OLED only in the dark areas of the virtual image. A liquid crystal based dynamic switchable optical shutter, in embodiments, may improve image contrast of the virtual image.

Additionally, OLEDs are very susceptible to the environment, especially that of humidity, moisture and sweat. For this reason, the OLED optical combiner can be over coated with ultrathin multilayer hermetic encapsulation coating. The coating can be, by way of example, Coat-X™; a Swiss company produces a product that comprises Silicon oxide/Parylene-C multilayers that are deposited at room temperature. This can make the see-through OLED one or more of, sweat resistant, water resistant, or waterproof. This can make a micro-lens array one or more of, sweat resistant, water resistant, or waterproof. This can make a micro-optics array one or more of, sweat resistant, water resistant, or waterproof. This can make an optical shutter one or more of, sweat resistant, water resistant, or waterproof. This coating can also be used for the electronic components of the Augmented reality or Mixed reality unit or system.
